Multiple Renders

Harmony lets you simultaneously render many formats and resolutions for a scene. This saves a lot of time as you do not have to return between each render to start a new one.

To use multiple renders, connect as many Write nodes as needed to match the required number of exports. Then, adjust each Write node’s settings to create image sequences or movies.

NOTE: YOU MUST GIVE DIFFERENT NAMES TO EACH OUTPUT FILE. This is especially important if you save them all in the same folder, so they do not overwrite each other.

When you have multiple Write nodes in a scene, it is useful to rename the nodes according to their output settings such as: low_resolution_movie or HDTV_sequence.

To export different resolutions concurrently, you need to create a combination of the following:

Write node—see Advanced Export

Scale-Output node

Crop node

Once your Write nodes are connected, you need some Scale-Output nodes to change the resolution output of the Write node. For example, if you export in a high resolution and a low resolution, you need one Scale-Output node.

Set the project’s resolution to the highest resolution needed for this export and use the Scale-Output nodes to scale down the other outputs.

DO NOT scale up the output size, that will not provide a good result. It is also better to use the Scale-Output node to scale down in a same aspect ratio so that it does not distort the image.

To output two files with different aspect ratios, such as 16:9 and 4:3, you can use the Crop node. This node is used to crop the final image in order to discard excess information without distorting the render.

If you start with a higher resolution and want to crop down to a lower resolution, such as HDTV to NTSC, you will need to combine the Crop node with a Scale node.

Once you know the type of render you want to do, you will need to retrieve your nodes from the Node Library and connect them to the scene’s network.
